Introduction

GB/T 16262.1-2025, GB/T 16262.2-2025, GB/T 16262.3-2025 and GB/T 16262.4-2025 Describes Abstract Syntax Notation One (ASN.1), which defines messages exchanged between peer applications. The encoding rules defined in this document apply to type values determined using the notation specified in GB/T 16262.1-2025. The encoding rules generate the transfer syntax for these values. These encoding rule specifications also implicitly apply to decoding. There are multiple sets of encoding rules for ASN.1 type values. This document defines the Permitted Encoding Rules (PER). It is a set of condensed coding rules because this set of coding rules is more comprehensive than the basic coding rules described in GB/T 16263.1-2025. (BER) and its derived encoding rules are more compact. GB/T 16263.1-2025 is a compact encoding rule specification for some parts. refer to. GB/T 16263 is planned to consist of eight parts. --- Part 1.Basic Encoding Rules (BER), Regular Encoding Rules (CER) and Untypical Encoding Rules (DER) specifications. To specify a set of basic encoding rules. --- Part 2.Specification of the compressed encoding rules (PER). The purpose is to specify a set of compressed encoding rules. --- Part 3.Encoding Control Notation (ECN) Specification. The purpose is to standardize the ASN.1 Encoding Control Notation. --- Part 4.XML Encoding Rules (XER). The purpose is to specify the Basic XML Encoding Rules (BASIC-XER), regular XML Encoding Rules Set (CXER) and Extended XML Encoding Rules Set (EXTENDED-XER). --- Part 5.Mapping of W3C XML Schema Definitions to ASN.1.The purpose is to define the mapping from any XSD schema to ASN.1 There are two versions of the mapping mode. --- Part 6.Registration and application of PER coded instructions. The purpose is to specify the PER coded instruction format, mechanism, registration agency Methods of operation, PER and ASN.1 related. --- Part 7.Octet Encoding Rules (OER) Specification. The purpose is to provide constraints for the Basic Octet Encoding Rules and Generates a unique encoding for any given ASN.1 value. --- Part 8.JavaScript Object Notation Encoding Rules (JER) specification. The purpose is to specify a set of JavaScript objects Representation encoding rules for applications that interoperate with JSON. Information technology ASN.1 encoding rules Part 2.Specification of the Reduced Encoding Rules (PER)

1 Scope

This document specifies a set of compact encoding rules that can be used to derive transmission codes for type values defined in GB/T 16262.1-2025. These packed encoding rules also apply to decoding such transfer syntaxes in order to identify the data values being transferred. The encoding rules specified in this document are. ---Used during communication; --- When choosing encoding rules, minimize the size of the value representation as the main consideration; --- For all extended forms described in GB/T 16262.1-2025, it is allowed to increase the value while retaining the encoding of the existing value. External values extend the abstract syntax; ---Can be modified according to ISO /IEC 8825-6.2021.
